W‐Based Thin Film Metallic Glasses Doped with Ni, Zr, and B for Industrial Applications

open access: yesAdvanced Engineering Materials, EarlyView.
This work is the first to deal with a comprehensive comparison of two metallic glass systems, W–Zr–B and W–Ni–B, in terms of their suitability for specific industrial applications. Their mechanical and tribological properties are compared and discussed in combination with structural homogeneity on different types of technically relevant substrates and ...

Investigation of Oxide Dispersion Strengthening Effect on the Strength of Diffusion‐Bonded AISI304 Parts

open access: yesAdvanced Engineering Materials, EarlyView.
Experiments for reinforcing the diffusion bonding plane by the oxide dispersion strengthening effect are presented. Small ceramic particles (0.5 and 50 μm, respectively) are incorporated. Furthermore, ceramic particles help to penetrate stable passivation layers, enabling atomic diffusion across bonding planes. Since a ceramic–metallic interface cannot

The role of 99mTc-Ubiquicidin (UBI) and 99mTc-IgG scintigraphies in diagnosis of acute appendicitis: A preliminary result [PDF]

open access: yes, 2014
Introduction: Appendicitis is one of the most common surgical emergencies. In spite of the relatively high rate of negative appendectomy, as a result of miss diagnosis, uncertainty of diagnosis still continues to challenge physicians.

Surface Modification of Sol–Gel Synthesized Ba0.85Ca0.15Zr0.1Ti0.9O3 using Stearic Acid Additives

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores a novel approach to enhance the piezoelectric performance of lead‐free BCZT ceramics synthesized via the sol–gel method. By coating the BCZT powder with only a 0.69 nm stearic acid layer, the electromechanical response is significantly boosted up to 359 pC N−1, revealing promising implications for high‐performance sensor and ...
